butternut squash (the longer the trunk of it the better for getting more fries. I used 1 small squash, but I was just making enough for myself. You can use however much you want.)
salt (coarse sea salt is best)
Pre-heat the oven to broil. My oven has low and high broil options, I used low.
Using a a strong vegetable peeler or knife. Peel the outside of the squash. Cut off the bulb shaped part of the squash. Cut the long part of the squash into skinny even fry like strips. They should be as uniform as possible for best results. If you make thicker fries you may need to bake them after the initial broiling at 400 degrees or until done.
Lay the fries out on a paper towel. Sprinkle evenly with FINE salt and let sit for 30 minutes. This helps the squash to 'sweat' and pull some of the water out. When they are finished sweating pat dry.
Place the fries on parchment paper on a cookie sheet. Broil the fries for a few minutes on one side. You want them to start getting a little bit of a 'skin' but not to burn. Take the pan out of the oven and using a spatula flip the fries over. Do the same for this side. You will need to keep broiling and flipping a few times to ensue even browning and dryness.
Everybody's oven is different, so cooking times will very. For this reason, it is normal to have some of the fries burn (the smaller thinner ones of the bunch, that's why uniformity is so important). You can take out the fries that finish early and continue to flip and broil till they are done.
If you find that your broiler is too hot, you can lower the oven rack. Just remember, the goal is to cook the fries quickly (as you would in frying) That way the inside doesn't have time to get mushy.
Butternut squash can burn easily, so toward the end of cooking keep a close eye on them or you will end up with a heap of charred squash. But don't take them out too soon either, be patient enough to let them get browned.
When finished sprinkle lightly with salt. Cool the fries slightly on a paper towel, spreading them out so they are not laying on top of each other. This will make them get soggy. Eat and enjoy!
